In a blender jar, add the whole spices, aromatics and chili peppers.
Now add in the kaffir lime and turmeric powder.
Add a handful of cilantro leaves with a bit of the stem portion too and give this a blitz.
Blend until the mixture is slightly coarse and looks like this. Transfer it to a jar and refrigerate.
Notes
To lend the curry paste that authentic flavor and texture, grind it using a mortar and pestle instead of using your blender. This may take a bit more time and effort, but it's totally worth it!
For extra flavor, dry roast the whole spices in a pan over medium heat until they turn aromatic, then take them off heat and let them cool down completely before you use them for the recipe.
When using lemongrass, make sure you chop out the tougher, fibrous portions of the stalks and just use the softer, white portion.
If the paste seems too try, you can add a splash of water into it to get it to a smoother, pasty consistency.
